The classes java.lang.Exception and java.lang.Error are subclasses of the class java.lang.Throwable. ArrayIndexOutOfBoundsException can occur due to many reasons like when we try to access the value of an element in the array at a negative index or index greater the size of array -1. Here you can see the first 555 elements of the array get printed but when we tried to access the 6th6^{th}6th element (that do not exists) an Exception is thrown and the program got terminated. Why is the federal judiciary of the United States divided into circuits? One way to avoid this exception is to be more specific when declaring the array. What is wrong in this inner product proof? An array in Java starts at index 0 and ends at index length - 1, so accessing elements that fall outside this range will throw an ArrayIndexOutOfBoundsException. . Therefore, whenever we try to access an invalid index the catch block will get executed and the corresponding error message can be printed to the console or/and exception can be thrown for easier debugging. Arrays are estimated at the hour of their confirmation, and they are static in nature. Developers who are unaware of this fact and try to add new elements run into the UnsupportedOperationException.

The index is either negative or greater than or equal to the size of the array. In this example, the denominator is explicitly assigned to zero, so it's obvious that a divide-by-zero error will occur. ArrayIndexOutOfBoundsException Question 3 30 seconds Q.

Using Try-Catch: Consider enclosing your code inside a try-catch statement and manipulate the exception accordingly.As mentioned, Java won't let you access an invalid index and will definitely throw an ArrayIndexOutOfBoundsException. When you iterate over a list, the underlying collection must be fixed and not updated. Save, Compile & Run the code. Java ArrayIndexOutOfBoundsException is produced when the array elements past a predefined length are accessed. Therefore, whenever we try to access the index out of the array bounds, the ArrayIndexOutOfBoundsException exception is thrown at the runtime, and the execution of the program gets terminated.
